Specification of Letters Patent.

Patented May 7 1918.

Application filed September 7. 1917. Serial No. 190,265.

To all whom it may concern Be it known that I, JOSEPH H. BEEDER, a citizen of the United States, residing at the city of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Vulcanizers, of which the followin is a specification.

This invention consists of an electric vulcanizer adapted to receive its heat from low-tension currents, particularly such, for instance, as are derived from storage batteries, magnetos, or the like on motor vehicles.

In the accompanying drawings forming part of this specification and in which like numbers of reference denote like parts wherever they occur,

Figure l is a to plan view, except the part that is in section, which is on the line 11 in Fig. 3, 4, and 5;

Fig. 2 is a section on the line 22 in Figs. 1, 3, 4, and 5;

Fig. 3 is a front end elevation;

Fig. 4 is a section on the line 44 in Figs. 1 and 2;

Fig. 5 1s a section on the line 5-5 in Figs. I

be wound more tightly together than is 1 and 2; and

Fig. 6 is a side elevation showing the vulcanizer upside down with a tube to be vulcanized resting in its groove while vulcanization takes place by means of the heat generated from the electric current introduced through the entering wires to wires of suitable resistance within the interior of the vulcanlzer.

The box or casing 1 may be made of cast iron or other suitable material adapted to receive and radiate heat.

This box is preferably provided with a pair of water pockets 2, separated by a partition, by which its temperature may be determine as water placed in the one of the said pockets turned upward will steam when the vulcanizer nears the temperature of 212 degrees Fahrenheit.

The groove 3 is adapted to fit the contour of either tubes or casings while resting upon or against the same duringethe process of vulcanization or, upon ing turned bottom side up (as shown in Fig. 6), to allow such articles to rest in the said groove.

The wires 4 and 5 lead from the magneto, storage battery, or the like to the binding posts 6 and 7, respectively, which pass through the entrance insulation composed of the sheets 8 and 9 of asbestos and plate nect with wire 11, which is of suitable resistance to give forth an abundance of heat.

Wire 11 is wound as closel as necessary or as may be desired aroun the cores or rods 12 of the frame composed of the same and of the end-pieces l3 and 14.

Preferably formed by ribs 15 and 16 is groove 17, in which end-piece 14 is adapted to be inserted and held when the abovementioned frame is introduced to the intcrior of casing 1 through the opening 18 within flange 19,, against which flange asbestos sheet 9 impinges, pressed thereagainst by glass plate 10, which in turn is pressed by asbestos 8, which is held by outside keeper-plate or lid 20, fastened by screws 21 to box 1. Apertures in lid 20 allow the passage of wires 4 and 5 to binding-posts 6 and 7 The rods 12 are socketed in any suitable manner in the end-pieces 13 and 14 or the frame composed of the said members may be made of one integral member.

It will be understood that the wire 11 may shown in the drawings.

The insulation at the entrance retains the heat, and keeps the vulcanizer hot even after the current has ceased to fiow.

In putting this device together, it is easy to find groove 17 at the rear end of casing 1 notwithstanding that it is invisible in the interior, because the said frame reaches all 10 of glass and at their inner .ends conthe way in and needs only to be moved slightly to locate the said groove.

In use, the repair work can be done on tube 23 or a casing while the vulcanizer is heating by current turned into wires 4 and 5 by a suitable switch. Then the repaired part to be vulcanized can be laid in groove 3 (as shown in Fig. 6) and left there in, for instance, the tonneau of an automobile for the night or .while the owner dines or is otherwise engaged, the heat continuing for I considerable (and the necessary) time after the current has been turned 0%.

Having thus described this invention, I hereby reserve the benefit of all changes in form, arrangement, order, or use of parts, as

it is evident that many minor changes may be made therein without departing from the spirit of this invention.

I claim:

1. In. a device of the character described,

the combination of a casing having a groove in its hollow interior, a frame adapted to fit into the said groove and to be contained in the said interior, a resistance wire borne by the said frame, means for holding the said frame at its end opposite the said end, insulation at the entrance to the said casing, and

electrical conducting means connecting with the above-mentioned wire.

2. The combination of a hollow casing, a removable frame located therein, an electrical resistance wire borne by the said frame, asbestos and glass insulation located at the entrance to the said casing, binding-posts that pass through-the said insulation, and electric wires connected to the said bindingposts, there being a flange against which inward movement of the said insulation is stopped.

3. The combination of a hollow casing, a removable frame located therein, an electrical resistance wire borne by the said frame, asbestos and glass insulation located at the entrance to the said casing, binding-posts that pass through the said insulation, electric wires connected to the said binding-posts,

therebeing a flange against which inward movement of the said insulation is stopped, and a keeper plate for clamping the said insulation into place.

4, The combination of a hollow casing, a removable frame located therein, the said frame being composed of a air of end-pieces and a plurality of longitu lnal members, an

electrical resistance wire borne by the said frame, asbestos and glass insulation located at the entrance to the said casing, bindingposts that pass through the said insulation, and electric Wires connected to the said binding-posts.

5. The combination of a hollow casing, a removable frame located therein, an electrical resistance wire borne by the said frame, asbestos and lass insulation located at the entrance to t e said. casing, binding-posts that pass through the said insulation, electric wires connected to the said bindingposts, and a Water pocket in the said casing.

In testimony whereof I hereunto aflix my signature.

JOSEPH H. REEDER.
